United States Patent 3,319,917 HOOK BRACKET FOR APERTURED BOARD Lucien.I. Bilo-deau, 71 Orange St., Barre, Vt. 05641 Filed Aug. 31, 1966, Ser.No. 576,293 2 Claims. (Cl. 248-225) This invention relates to a methodof mounting a bracket on an apertured board.

Various attempts have been made to provide locking means so as to hold abracket on an apertured board. These have usually consisted of aseparate latching means mounted on the upper and lower part of thebracket to engage and hold two engageable holes in the apertured board.These separate locking means have many disadvantages, the principal onebeing that they become disassociated with the bracket and are notavailable for use when desired. Such locking means are shown in UnitedStates Patents Nos. 3,241,799 and 2,961,724.

It is an object of the present invention to provide a unitary bracketfor mounting on an apertured board.

It is also an object of the present invention to provide a brackethaving an upstanding gripping means asso- 'ciated with the top thereofand an upstanding gripping means associated with the bottom portionthereof.

It is a still further object of the invention to provide a unitarybracket mounted on an apertured board that is so constructed as to allowthe insertion of an upstanding support on the upper end thereof and anupstanding support on the lower end thereof.

The various features of novelty which characterize this invention arepointed out with particularity in the claims annexed to and forming partof this specification. For a better understanding of the invention,however, its advantages, and specific objects obtained with its use,reference should be had to the accompanying drawings and descriptivematter in which have been illustrated and described a preferredembodiment of the invention.

In the drawings:

FIGURE 1 is a perspective view of the bracket.

FIGURE 2 is a front view of the bracket mounted on an apertured board.

FIGURE 3 is a side view partially in section, taken on line 33 of FIGURE2, showing the bracket in the locked position.

FIGURE 4 is a view similar to FIGURE 3, showing the bracket in theunlocked position.

FIGURE 5 is a rear view of the bracket, shown in FIGURE 1.

FIGURE 6 is a top profile view of the bracket shown in FIGURE 1.

A bracket 19 comprises an upper front surface 11 and a lower frontsurface 12, the surface 11 having a protruded rigid book 13 madeintegral therewith. The upper portion 11 and the lower portion 12 havethe thin section 14 therebetween. This thin section 14 acts as a hinge,allowing lower portion 12 to move under force with respect to the upperportion 11. Protruding rearwardly from the upper marginal face of theupper portion 11 is the support bar 16 having its extreme outer end 17returned upwardly forming an upper retaining book. The length of theportion 16 must be at least the thickness of the apertured board towhich it is to be attached. The lower surface 12 has the marginalportion 18 defining the lower portion of the bracket 10. Integrally withthe rear face and upstanding from the rear surface thereof is a curvedhook portion 20, the center of curvature of this hook portion being thethin section 14 and the hook portion 20 being an arc of the circlehaving its center at said thin section 14. The said thin section may befrom 30 to thousands of an inch and semi-circular in form depending onthe composition of the plastic from which it is molded. Polypropyleneand polyethylene have both given satisfactory results depending on theamount of plasticizer used.

When mounting the bracket 10 on the apertured board 21, having apertures22, 23 and 24 arranged in parallel alignment through said board, thebracket 10 is so placed that the outer end 17 of the upper hook isreceived by and passes through the opening 22, then the support bar 16is received in the opening 22 and upon forcing the bracket 10 downwardlyit assumes the position shown in FIGURE 4. The curved hook '20 assumes aposition shown in FIGURE 4 and upon forcing the lower surface 12downwardly the curved hook 20 is received in and held by the opening 24,as shown in FIGURE 3. The support bar 16 of the upper hook and thecurved hook 20 grip the body portion of the apertured board so as tohold the bracket 10 in contact therewith and prevents the movement ofthe bracket due to the reception of a weighted object on the hook 13.

There are many advantages to mounting a device of any type on anapertured board by means of two hooks on the back of the device whichwill protrude through and overlap the back surface of the aperturedboard. This method of mounting holds the device in close contacttherewith and prevents movement of the device on the surface of theboard regardless of the type of force applied, that is, the device willretain its position on the board even if the force is up, down orsidewise.

In the hook used as an example in this application all of the stressproduced by loading the hook 13 is transmitted through the bracket tothe hook portions and therethrough to the apertured board. The upperhook has the supporting portion 16 and the outer end portion 17extending upwardly when used in conjunction with the lower curved hook20 which also extends upwardly in the same direction as the portion 17of the upper hook, these hooks being a portion of the integral bracket10.

While in accordance with the provisions of the Statute, the best formsof embodiment of this invention now known have been illustrated anddescribed, it will be apparent to those skilled in the art that changesmay be made in the forms of the apparatus disclosed, Without departingfrom the spirit of this invention, as set forth in the appended claims;and in some cases certain features of this invention may be used toadvantage without a corresponding use of other features.

What is claimed is:

'1. A bracket for use in combination with an apertured panel, saidapertured panel having opposed face surfaces, and having spacedapertures therethrough, said bracket having an upper and a lower hook,

(a) the upper hook comprising an elongated support member with anupwardly protruding outer end,

(b) said unitary bracket having a thin section therein between the upperand lower hooks,

(c) and the lower curved hook being upwardly curved and rotatable aboutthe center of the thin section adapted to be received in and held by asecond aperture in said apertured panel.

2. A bracket as set forth in claim 1, wherein said upwardly curved lowerhook is an arc of a circle having its center at the center of the thinsection.
